I'm trying to run sudo apt update

And I get this message E: Malformed entry 1 in list file /etc/apt/sources.list.d/ros2-latest.list (Component) E: The list of sources could not be read.

Here is /etc/apt/sources.list.d/ros2-latest.list content:

deb [arch=amd64,arm64] http://repo.ros2.org/ubuntu/main main

Here is sources.list content:

Since you don't show us the content of `/etc/apt/sources.list.d/ros2-latest.list` it is difficult to to say whats wrong.

Is it sources.list file or something else?

It is a malformed entry in that file.

If you post the contents of that file to your question, someone will tell you what is wrong. That's what everyone is telling you.

Ahmed Ismail

I updated the question with sources.list content.

Why don't you read comments and your own question? We need contents of another file. You got an error message that something is wrong in `/etc/apt/sources.list.d/ros2-latest.list`. You're asking to help you to find out what is wrong. Why is it so difficult to provide contents of that file?

Ahmed Ismail

Sorry I told you that I'm completely new to Ubuntu, I didn't mange to access this file at first as I told you. But I did and updated the question with its content.

@AhmedIsmail You updated with the contents of the wrong file. Look at your error message, it clearly states which file is wrong: `/etc/apt/sources.list.d/ros2-latest.list`.

The line in /etc/apt/sources.list.d/ros2-latest.list is wrong.

Change it to

deb [arch=amd64] http://repo.ros2.org/ubuntu focal main

You can do it by running

sudo nano /etc/apt/sources.list.d/ros2-latest.list

Ctrl+O to save Ctrl+X to exit.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
